Why is Shanthi Gears falling/rising?

As of 18-Sep, Shanthi Gears Ltd. is experiencing a price increase, currently trading at 562.00, which reflects a rise of 5.5 or 0.99%. The stock has shown a positive trend, gaining 2.18% over the last three days and outperforming its sector by 0.85% today. Despite a slight decline in delivery volume, which fell by 18.91% against the 5-day average, the stock remains liquid enough for trading. Additionally, the company boasts a low debt-to-equity ratio and has demonstrated healthy long-term growth with an annual operating profit increase of 68.91%. However, it is important to note that the stock has underperformed over the past year, with a decline of 6.33%.
In the broader market context, Shanthi Gears' short-term performance over the past week shows a return of 0.36%, which is significantly lower than the benchmark Sensex's return of 1.80% during the same period. While the stock has performed well over a three-year and five-year horizon, its recent underperformance relative to the benchmark indicates that it may not be keeping pace with overall market trends. This discrepancy could be contributing to investor caution, despite the company's strong fundamentals and recent price gains.
